Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Fuel System Issues

2.1 Check Fuel Injectors

Remove the engine cover (if applicable).
Disconnect the fuel injector connectors.
Use a fuel injector cleaning kit to clean the injectors.
Reinstall the injectors and reconnect the connectors.

2.2 Replace Fuel Filter

Locate the fuel filter (usually along the fuel line).
Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using a line wrench.
Replace the old filter with a new one, ensuring correct orientation.
Reconnect the fuel lines and install the fuel pump fuse.

3. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires.
Using a spark plug socket, remove the spark plugs.
Inspect each plug for wear or carbon buildup and replace if necessary.
Torque new spark plugs to manufacturer specifications (typically 13-20 lb-ft).
Reinstall ignition coils or spark plug wires.

4. Replace Air Filter

Locate the air filter housing and open it.
Remove the old air filter and clean any debris from the housing.
Install the new air filter and secure the housing.
